Potato - Tubers

The part of the potato plant we eat is called the tuber,
which is actually an enlarged underground stem. Each plant
will produce multiple tubers. Potato tubers come in a
variety of colors, but most common are red and white. Their
shape can be round, oblong, flattened, or elongated.

An identifying feature of potato tubers is their "eyes,"
which are small nodes with buds. If placed in a warm
location the buds will sprout. If tubers are exposed
to light, the buds will turn green as well as the tuber
itself.
